x86: ich-spi: Fix a bug of reading from a non-64 bytes aligned address
The ich spi controller driver spi_xfer() tries to align reading
address to 64 bytes when doing spi data in, which causes a bug of
either infinite loop or a huge size memcpy().
Actually the ich spi controller does not have such requirement of
64 bytes alignment when reading data from spi slave devices.
